Ranked #1 based on expert reviews, user sentiment, and value analysis.
Pros
- Highest security rating available
- 18mm hardened steel resists bolt cutters
- Anti-theft protection guarantee
Cons
- Very heavy at 4.55 lbs
- Small shackle limits locking options
Don't buy this if…

Excellent
Consensus

Ranked #3 based on expert reviews, user sentiment, and value analysis.
Pros

- Good security at a reasonable price
- Key registration for replacements
Cons
- 12.7mm shackle is vulnerable to large bolt cutters

Don't buy this if…

Excellent
Consensus

Ranked #4 based on expert reviews, user sentiment, and value analysis.
Pros
- Compact folding design for easy transport
- Hardened steel bars resist cutting
- Includes frame-mounted carry bracket
Cons
- Folding joints are potential weak points
- Heavier than cable locks
Don't buy this if…

Pros
